For users who want to download their photos, anyone with tens of thousands of them will have to spend some time on the task.

Users can download 500 pictures at a time, which are sent in a .zip file to their Flickr inboxes. Clicking on the file downloads and stores it.

"While current free users with over 1,000 photos and videos will become eligible for deletion starting tomorrow, users may not see any of their content deleted immediately," said Allen Nguyen, a consultant for Flickr, in an email to NBC 7 Monday. "The first accounts to be impacted will be abandoned accounts that bear large volumes of private photos."
